Yes on the exhaust manifolds but the cat should either be welded or bolted on after your Y pipe then goes to your cat!
Your catalytic converter is at the top of your motor at the exhaust manifold take out the 4 14mm screws that connect your converter to your manifold drop down out the bottom of engine and replace another really simple fix
The catalytic converter on a 2004 Pontiac Grand Prix is located under the vehicle. To remove it the bolts which connect it to the exhaust manifold must be removed. The bolts which connect it to the other piping will need removal as well. After all mounting hardware is off the converter will come off.
Crawl under the vehicle and find the exhaust pipe coming from the engine. It will connect to the catalytic converter and from there to the muffler.
Ill assume that yours cracked. You have to purchase a replacement manifold with a catalytic converter bolted up to it. It is usually a one piece set up. It costs about $300 after market or about $500 OEM from Honda. To replace it: -Remove the primary o2 sensor with a 22mm socket -Remove the secondary o2 sensor at the end of the catalytic converter -Remove the 12mm bolts that connect the manifold to the head -Remove the 14mm bolts with spring that connect the down pipe to the exhaust -Wiggle it out through the bottom or the top -Reinstall the new one using these steps but in reverse.
It is the pipe that starts from your front manifold and crosses from right to left and the pipe continues to the back where it bends down to connect to your CAT converter. Hope that helps.
The check engine light will illuminate. The code(s) that are set will tell you what's going on. The only check you can perform yourself is for a blockage in the exhaust system as a whole. This will not diagnose a problem specific to the converter, but plugged converters are possible. The test is simple: connect a vacuum gauge to read intake manifold vacuum. Then start the engine and note the reading at idle. Bring it up to 2000 RPM. Now release the throttle quickly (while watching the vacuum gauge). If there is restriction, the reading will either, never rise above 5 in Hg (measure of vacuum, 'in Hg' means 'inches of mercury') above the normal (idle) reading, or will seem to hover around the highest reading for a moment before returning to normal. Again, this does not necessarily mean a catalytic converter problem, the restriction could be a plugged converter, or a banana in the tailpipe (yes, it's happened), or some other blockage. Also worth noting, a rotten egg smell associated with the exhaust is sometimes, but not always, an indication of a failing or failed catalytic converter.
The purpose of the exhaust manifold is to connect the exhaust ports on the cylinder head to the exhaust pipe.
To connect a digital TV converter box, follow these steps:1. Disconnect antenna from TV2. Connect antenna to antenna connection on Converter box.3. Connect an antenna cable from the converter box to the TV's antenna connection.4. Turn the TV to channel 3, turn on the converter box, and follow the setup menu from the converter box to search for channels.5. Keep the TV on channel 3, and change channels using the remote control for the converter box.
It shouldn't make any difference except that you should now make fewer exhaust hydrocarbon emissions. It isn't the Cat Converter, look somewhere else. Connect a code reader to find out what problem codes are stored in the computer.
you can't
What kind of digital converter? Digital TV converter? Digital sound converter? Video converter? So many different analogue sources can be converted to digital... ...and there is usually a converter available or that can be made to work.
you get a qualified engineer to do it !
